2009 Yukon SLE electrical problems. It had a bad battery for several weeks, slow starts, and it had to be jumped several times. I didn't have the money to replace it so I had to deal. It started acting up and on the last leg of the battery the Transmission ended up going into limp mode. I've had zero problems with my truck previously and its been an awesome ride. I Was told to replace batteryand check fuses under the hood in the main fuse box. Replaced with new battery and checked fuses. Half of the all the fuses showed no current running to them, including TCM fuse and Transmission ignition module fuse along with several others. Replaced all fuses with new fuses, except for the relays. I don't know if those are blown or how to check them. Once the new fuses were put it, they still show no current running to them. I took it to auto zone. They hooked it up to the scanner and its throwing no codes at all. You would think there would be at least something. Especially since my transmission is in limp mode. Something is really wrong. I called a couple of shops. They all say electrical. Possibly a blown fuse box or wire harness but they want to see it and they all want money. I have left the cables off the battery every night to possibly reset the PCM but still the same thing. Is there is anything I could possibly do or check on my side before I take it in? I'm at a loss with only one vehicle and I'm at risk of blowing my transmission. Any advise would be greatly appreciated. Thanks Y'all!
